摘　　要：基于已有的结构抗倾覆研究,对窄基铁塔基础的倾覆公式进行了探讨,采用极限平衡法对倾覆验算公式进行推导,将推导公式与有限元模拟的结果进行了对比分析。结果表明,采用推导公式计算得到的抗倾覆弯矩符合实际工况,验算修正公式可为工程设计人员提供参考。Based on the current anti-overturning studies for other structures, this paper discussed the anti-overturning formula for narrow-base towers, which was derived with method of limit equilibrium analysis. The comparative analysis between anti-overturning formula and finite element simulation were studied. The results show that the anti-overturning bending moment obtained from the formula is accord with the actual working condition, and the checking and correction formula can provide references for the engineering design.
